AC sanitisation applies an approved antimicrobial treatment to the coil, drain pan and blower to kill mould, bacteria and viruses living inside the unit — something a standard clean, which mainly removes dust, doesn't fully address.
Why Clean Air Depends on More Than Dust Removal
A home can look and feel clean while the AC unit circulating its air is carrying biological growth on the coil that a routine wipe-down never reaches. Since the AC is the single largest volume of air moved through a home each day, whatever's living inside it has an outsized effect on the air quality of every room it serves.
What Sanitisation Adds Beyond Cleaning
Sanitisation follows a physical clean with an antimicrobial or disinfectant treatment applied to the coil, drain pan and blower wheel, specifically targeting the mould spores and bacteria that a water rinse or dry wipe leaves behind. It's the step that addresses persistent musty odours that survive a normal cleaning.
Who Benefits Most
Households with allergy sufferers, asthma, young children or elderly family members see the clearest benefit, since they're most sensitive to whatever's being recirculated through the air. Health-focused spaces like clinics and nurseries typically schedule this on a routine basis rather than only when a problem is noticed.
If this sounds like what's happening with your unit, our AC Sanitisation page covers exactly how we handle it, or you can message us directly for a same-day assessment.
Frequently Asked Questions
Is AC sanitisation safe for homes with children?
Yes, when carried out by a professional using approved products designed for indoor use; the treated surfaces are inside the sealed AC unit rather than directly in living spaces.
How is sanitisation different from a normal AC service?
A normal service focuses on mechanical function and dust removal; sanitisation specifically targets biological growth with an antimicrobial treatment.
How often should AC sanitisation be done?
Twice a year is a reasonable baseline for most homes, with more frequent treatment for health-sensitive spaces or units that develop odour issues repeatedly.
